Abstract

A safety device is described, particularly for a thermostat (1) with an immersion rod system comprising a rod (2) realized with thermoexpansible material, a low thermal dilatation rod (3), provided within said thermoexpansible rod (2), a casing (8), within which said rods (2;3) are introduced, in correspondence of a cavity or cup (7) realized in thermoconductive material, and an interruption mechanism (4) to interrupt a phase of the electric circuit, connected to said rods (2;3), said device comprising a spring element (6), a thermally inert thin disk (9), a calibration element (10) for the safety device and an element (11) for transmitting the strains of the inert disk element (9) to an interruption mechanism for both the phases of the electric circuit, said elements being introduced, in the above mentioned sequence, from the bottom to the above along said low thermal dilatation rod (3), with the calibration element (10) that is regulated in such a way to make the safety device intervening at a temperature higher than the intervention temperature of said interruption mechanism of a phase of the circuit, and said inert disk (9)element being realized with a concavity toward the bottom and having features to trip upside, reversing its concavity, following the dilatation of the thermoexpansible rod (2). <IMAGE>
